Talend and Text Mining with SVD

Anonymous — Sat, 16 Nov 2024 10:45:12 GMT

Hi
We had a done a POC which consisted of Text mining in R. The R code used to create the matrix of occurrence of each word in the document and then do the SVD caclulations. The output from this was fed to Analytic models.
Now our question is - does Talend have something that be used to do SVD? We do not want to use R in the production and want to development everything using Talend. So has anyone done something like this or can throw some light around what are the possible options here?

Hi Kirti,
For this SVD caclulations, could you please elaborate your case with an example with input and expected output values?
Best regards
Sabrina

Since you can use any Java in Talend take a look at the Apache Commons SVD
